Abstract

Enantioselective electrophilic fluorination of β-keto ­esters with Selectfluor® catalyzed by DNA and a nonchiral ligand-Cu(II) complex is presented. The chirality transfer from DNA to the substrate appears to be caused by the intercalation or groove binding of the substrate-ligand-Cu(II) complex to DNA.

Both st-DNA and calf thymus DNA are too large to be discussed in detail the transition-state structure of the immediate. Experiments using synthetic, structurally well-defined DNAs are now under investigations to confirm the actual transition-state structure.
